heads #3795896

Postby adumb on Mon May 04, 2009 2:44 pm

i have some local to me on craigslist. i am wondering if these would be a plus or not for me.

from jimsperformance.com

3795896 60cc 1.72 1.50 1958-72
283/307/327

idk if that would make too much compression or if they'd even work at all for my car. thanks.

EDIT: the add is stating they have 2.02 valves.

These aren't the double hump heads. So you're making a lot of compression and not much power. That's the problem with 327 heads. Flat top pistons would be out of the question for a street build. I personally wouldn't go those heads, but it depends on what kind of results you want for the price.

Circle track guys love those 416's, some 601's too. Depends on what they come off (for the 601's anyway).
